Paul Klee is a German painter, (1879-1940). Unlike many of his contemporaries, Klee does not adopt the style of the Impressionists to then overtake them, but he checks out their principles pour integrate them into his own experience. Light, which is the instrument of every representation as conceived by the Impressionists, was not for him linked to the problem of colour; he was more preoccupied by problems of tonality and he had a clear leaning for musical syntax. This, made up, now of tonalities, intensities, chromatics in a minor or major key, now of rhythms, tonic accents or semibreves enables the composition of a score of signs where visual harmony and counterpoint reign. Here, in this painting, there is very little figuration, one has to allow oneself to be penetrated by the luminous intensity of each coloured fragment, to be immersed in the spaces created by the repetitions and the scansions and to be lulled by the movements which make the eye move from one detail to the other; to abandon oneself to pure sensitive contemplation, with thought.
